60-30-10 Colour Ratio

Turn the 60-30-10 rule into real square metres of colour for your room.

How this works

Designers split a room into 60% main colour (walls, big rug), 30% secondary colour (sofa, curtains, a feature wall) and 10% accent (cushions, art, lamps). We take your walls plus floor as the visible colour area and split it in that ratio.
